You can use a leaf stencil or sketch out your own shape.
Or you can download these two images, cut them out and use them to trace the shape onto the printed paper.
These would also make interesting napkin rings (just attach a new elastic band to the underside), table scatter for a elegant fall table or place cards for Thanksgiving dinner if you write the names of your guests on them. My daughter suggested hanging them in the window and turning them into a mobile. How about making them into a autumn themed garland?
Can you think of any other ideas?
